Cayin RU7 Full Balanced Resistor Networks Discrete 1-Bit DAC Dongle Amplifier with Customized Leather Case

Feature:
Fully Balanced Resistor NetworksDiscrete 1-Bit DAC for DSD Format
Purposively designed micro-miniaturized 1-bit DAC circuit from discrete componentsConvert digital signal to analogue signal through a fully differentiate 4-chDAC architecture
The 1-Bit DAC circuit is a resistor network composed of 128 pcs (4 x32) highprecision Thin Film Resistors, this is closely resemble to the discrete DAC ofour N7 DAP
The output of the resistor network will go through a 3-level active LPF andthen converted to single-ended signal for volume adjustment.

High Power Parallel Phone Amplifiers
Dual amplifiers in parallel,providing 4-CH high powerBalanced Driven output
The second phone amplifieris a parallel unity gaininverting phase amplifierAn impressive upgrade inphone output power :
3.5mm SE, 160mW @32Ω4.4mm BAL, 400mW @322

Shared Line Out Conveniently Connected
The shared line out function wilconfigure the 3.5mm or 4.4mmphone output into fixed voltageoutput (bypassing volume control):3.5mm Single-ended, 1.2Vrms4.4mm Balanced, 2.4Vrms
11. 2HHz
18ItOAC
RU7
The line out voltage are carefullyselected to retain as much detailsand dynamic of the 1-Bit DAC withminimum noise and distortion.
Enable you to connect the RU7 toportable/desktop amplifier or homeaudio system and used it as anminiature 1-Bit DAC

Discrete Volume Contro!
Discrete Resistor Network DAC circuit is very demanding on incoming dataintegrity, we recommend users to keep the digital volume of mobile phoneat full output to safeguard the quality of audio digital signal.When off-the-shelf analogvolume options cannot meet highprecision, low noise, low powerconsumption requirement of RU7we developed our own discreteresistor network volume control.

Outstanding Digital Audio Capability withUser Selectable All-to-DSD
RU7 supports PCM up to 384kHz and native DSD from DSD64 to DSD256Its Audio Bridge will receive different audio format and go through highprecision signal enhancement.
All digital audio signal will convert to designated DSD format(DSD64/DSD128/DSD256) before feeding to the discrete 1-bit DAC circuit.

Low Power Consumption
Compatible with Common Platforms
Discrete resisotr network is a low-power DAC circuit when compare to otherhighly integrated DAC chipset, minimise power drain from mobile source.Redesigned amplification circuit increase output power dramatically whilemaintains the overall power drain at 100-110mA
Low power consumption allows RU7 compatibles with the following digitalaudio sources:"Android based mobile devices
"iOS and iPad OS mobile devices
*macOS computers
Window 7/8/8.1/10 computers
·Digital Audio Players with USB Audio output
